WASHING MACHINE.

Application filed August 31, 1920. Serial 510. 407,289.

To all whom it may concern:

Be it known that I. AnoLr K. HANSON, a citizen of the United States,residing atChicago, in the county of (look and State of Illinois, haveinvented a new and useful Improvementin Vashing Machines, of which thefollowing is a specification.

This invention relates particularly to washing-machines which areadapted for use in apartments, or where the conveniences of an ordinarylaundry cannot be had,

The primary object is to provide a washing-machine which can be mountedin a bath-tub and conveniently operated therein.

A further object is to provide a machine of this character which may becompactly stored, when not in use.

The invention is illustrated, in its preferred embodiment, in theaccompanying drawings, in which- Fig. 1 represents a plan view of theimproved machine mounted in a bath-tub; Fig. 2, an end view of thewashing-machine. the actuating mechanism being shown in section; Fig. 3,a vertical sectional view of the washing-machine, taken as indicated atline 3 of 'Fig. 2; Fig. 4, a vertical sectional view, taken as indicatedat line 40f Fig. 3; and Fig. 5, a broken sectional view showing a detailof the perforate clothes-holder employed.

In the illustration, A represents a bathtub; and B the improvedwashing-machine combined therewith. V

The washing-machine comprises a casing B e uipped with adjustablesupporting arms a perforate rotary cylinder B? mounted in the casing;and actuating mechanism B for the cylinder B The casing B may be .of anysuitable form. It is shown as provided with a removable top 1. The armsB project laterally from the upper portion of the casing B. The casingis provided with end flanges 2 between which and studs 3 the supportingarms B at one side of the casing are slid ably adjustable. The slidablyadjustable arms B are provided with longitudinal slots 4 through whichextend threaded studs 5 which project from the ends of the casing andare equipped with thumb-nuts 5'. By

this means, the arms B may be adjusted, so that the hooked extremities 7thereof may engage the upper edges of the lateral walls of the bath-tub.Two of the arms B are pivotally secured by similar studs and nuts nipple16 fitted with a stop-cock 16.

' 5 and 5. When the washing machine is cylinder is equipped at one endwith a trunnion 9 which is received in an interior bearirig 10 which isopen at its upper side to adm1t the trunnion. At its other end, thecylinder isequipped with an angular-stud 11 which fits into a, socket 12provided at the inner end of a trunnion 12, which extends through abearing 13 formed integrally with a gear-casing 13 which is supported bybrackets 13 secured to the end of the casing. The trunnion 12 hassecured to its outer end a worm-wheel 14.- which is housed in thegear-casing 13 and with which meshes a worm 14: which extends parallelwith the end of the main casing. The worm 14 is provided with asocket-end 14 which receives the angular end of the shaft 15 of anelectric motor 15 which is suitably .supported on the end of the maincasing B.

At one end of the casing B is provided a.

nipple is detachably connected with the faucet of the bath-tub by meansof a hose 17. The casing B is further provided with a drain-passage 18,which is suitably stoppered when the machine is in use. machine isprovided somewhat above the bottom of the casing with a discharge-spout19 controlled by a stop-cock 19. The perforations 8 in the rotarycylinder B preferably are formed in the manner illustratedin Fig. 5,that is, the metal wall of the cylinder is struck inwardly, as indi-*the cylinder as the cylinder rotates The This Also, the

cated at 20, and is perforated; and the metal surrounding theperforation is curled outwardly, or beaded, as indicated at 20 Thebeaded portion is received in the recess or depression 20 which isformed by striking the metal inwardly. In this manner, the bead is flushwith the outer surface of the cylinder .and only smooth metal ispresented at the inner-surface of the cylinder. If desired, the cylindermay be equipped with the usual internal radial projections 21 whichserve to engagethe clothes.

the cylinder is rotated by means of the electric motor until the clotheshave been washed the required amount. The suds may then be drained fromthe casing or tub of the washing-machine into the bath-tub through theoutlet 18. This outlet may then be closed and rinsing water may beallowed to run throu h the hose 17 into the casing B, the over ow 19being open at this time, if desired. The cylinder maybe operated untilthe necessary rinsing has been effected, after" which the water may bedrained from the casin B through the port 1 8.

The cy inder B is shown provided with a closure 22 which is hinged at 22and fastened in the closed position by means of a knob 22". The closuremay be applied in any desired manner, however. In the illustrationgiven, the casing B is shown provided at its ends with handles 23; andthe top 1 of the casing is shown provided with a handle 24.

It is to be noted that the washing-machine body is suspended in thebath-tub in such manner that practically the whole Weight of thewashing-machine is below the level of the arms B Thus, theWashing-machine is very stably and staunchly supported in a very simplemanner. Moreover, the source so of water-supply for the bath-tub islikewise available for use in small apartments, in

rooms for light housekeeping, etc., where usual laundry facilities areimpossible or are not readily available. As may be readily surmised,there is a large field of usefulness for the improved machine, andhitherto there has been no machine adapted to the field.

The foregoing detailed description has been given for clearness ofunderstanding only, and no unnecessary limitations should be understoodtherefrom, but the appended claim should be construed as broadly aspermissible in view of the prior art.

What I regard as new, and desire to secure by Letters Patent, is-

In means of the character set forth, the combination of a casing, twopairs of foldably mounted arm's connected with-the top of said casingand adapted to support the casing in a bathtub, one of said pairs beinglaterally adjustable, a rotary member mounted in the casing, andactuating mechanism for said member mounted on one end of said casin gADOLF K.
